What do you think is the largest Volcano eruption the world ever had ? Pinatubo (1991) ? Krakatau (1883) ? or even Tambora (1815) ? If your answer is one of them, you’re awfully wrong.
According to Discovery Channel, using 1 to 7 scale of VEI (Volcanic Explosive Index) they're sitting on 2nd, 3rd and 5th level of the scale. So, what tops the list ? as you might think, Yellowstone Caldera sits on 2 top of the scale by its eruption 640.000 years ago and 2.1 millions years ago.
Yellowstone is a US National Park lies on the corner of Wyoming. The volcano beneath the park has been categorized as a Supervolcano. Supervolcanoes are classified as volcanoes that spew out more than a trillion tonnes of material when they erupt - equivalent to 30 Krakataus. Such volcanoes cannot be studied directly as the most recent was Toba in Sumatra around 71,000 years ago.
So, what’s the bad news dude, according to BBC Yellowstone predicted to erupt regularly every 600.000 years and you know, it’s now overdue.
When supervolcanoes blow they can cover entire continents with ash. But how this happens has been a puzzle because wind and the initial force of the eruption are not enough to carry the ash over such long distances. Now an examination of prehistoric eruptions has come up with an answer.
So Peter Baines from the University of Melbourne, Australia, and Stephen Sparks from the University of Bristol, UK, used geological records of ash volume and magma chamber size to estimate the energy of past blasts and model the plumes they would have generated. From this they deduced that the Earth's rotation fans ash out into a giant spinning cloud up to 6000 kilometres wide within one day. "It is a bit like a hurricane, but on a much larger scale," Sparks says.
Science report - "The magma chamber that was found extends basically beneath the entire caldera. It is approximately 40-50 kilometres long, approximately 20 kilometres wide and it has a thickness of about 10 kilometres. So it's a giant in volume and essentially encompasses a half or a third of the area beneath Yellowstone National Park."
This may be very significant to the End Days with "fire and brimstone" in large quantities. In recent years it has been discovered that Yellowstone is one of a few known examples of a supervolcano. These volcanoes erupt only rarely; but with a force at least 1000 times that of ordinary volcanoes.
Imagine 1,000 volcanoes all erupting in the same place at the same time.
While Krakatau ‘blew’ 36 cubic miles of debris, it causes the worlds’ temperature to drop by 5 degrees Celsius. Even causes the snow to fall on London in June (remind me to the first line of ‘Save the best for last’ song by Vanessa William). The eruption of Yellowstone has been predicted to drop the world’s temperature by 25 degrees celsius. And what do you think would happen then ? I can’t even imagine.
